ABSTRACT:
A cylinder bore for an internal-combustion or the like engine, having additional valve ports and an additional combustion chamber machined inside the cylinder wall, is disclosed. Said cylinder bore enables excellent volumetric efficiency and a two-step combustion process which comprises burning of two air-fuel mixtures having different compression ratios and different air-fuel ratios. Increased air provided for the combustion process and better distribution of combustion pressure will result with much more power delivered by engine and less emissions released into the atmosphere.
